No, you are certainly not crazy(well not for calling 911 anyway) lol
As far as the job goes, you must ask yourself a few questions though. Do you really want the new working times and conditions? Is it really more important than your relationship? If everyone really does think you're an idiot and the management is mad, is this where you really want to work? If you accept this crap now what will they throw at you in future? If you was out of work is this the sort of job you would apply for?
I think my opinion may be obvious but in case it's not ask yourself one more. Can I accept all of this and keep a good level of self-esteem and respect from everyone concerned?
thanks for the replies. The first week in the new job didn't go too badly, though the final night, Saturday was about as bad as I thought it would be. We were constantly busy and it was just physically draining even though I just sit at a computer for eight hours.
I really need to think about whether I want to stay there, like Jethro said. Unfortunately I am in a highly specialized field (which pays fairly well at my current workplace) and there's nothing similar within an hour's drive, at least in our lousy local economy. So once things settle down, I am going to look at what my options are if I want to move into a different type of job.
